A TYURNEYS Patented June '27, 1933 FFECE Lo UIs' H. ROW-LAND, onCINCINNATI, onio connnsronnnncn UNIT Application filedluly 11,

My invention relates to correspondence units and'particularly to meansfor facilitating the filing and removal of papers therefrom and to meanspermitting the units to be built up into stacks or tiers.

Correspondence units of this type previously constructed have been sodesigned as to make it diflicult for papers to be removed with facilityor have provided no means for preventing papers from becoming blown fromthe unit.

The principal object of my invention is to providea correspondence unitin which papers may be filed without chance of their becoming blown outof the unit and in which meansare provided for facilitating removal ofone or more of the papers.

Another object of my invention is to provide such a unit which is soconstructed as to permit several of these units to be secured oneuponthe other where greater amount of filing space is required.

Another object of my invention isto accomplish these new featureswithout any 5 greater cost than is required in constructing othersimilar units without these advantages.

In the particular embodiment of my invention selected for illustration:

Figure 1 is a top planview of one of these units,

Fig. 2 is a front elevation,

Fig. '3 is a plan of the blank from which i one of the units ismade,

Fig. 4 is a front elevation of two of the units secured together in onemanner,

Fig. 5 is an elevation of several of the units secured together inanother manner,

Fig. 6 is a detail of one of the spacers and the means for securing theunits together as shown in Fig. 4, and V Fig. 7 is a detail of the meansfor securing the units together as shown in Fig. 5.

Referring now to the drawings, each of these units is composed of abottom member 10, the front part of which extends inward arcuately sothat papers may be grasped by the fingers from the front of the unit andremoved readily. The unit has side walls 11 and rear wall 12, all ofwhich have the turned over edges or flanges 13 which prevent 1930.Serial no. 467,280.

the papers being blown out of the unit, yet allows the papers to fall byflexure down into the unit when laid thereon. Suitable feet 14,preferably made of rubber or some similar material, prevent the bottom10 from resting on the desk orother member where the unit is used. 1

. Referring particularly to Figs. 1 and 6, the turned over edges orflanges 13 of the walls and bottom 10 are provided with alignedapertures 15 and 15 respectively. Spacers 16 are fastened in the bottomapertures 15 and are secured by nuts 17 in the flange apertures '15 ofalike unit holding two of the correspondence units together.

Referring particularly to Figs. 5 and 7, the units are secured togetherdirectly by means of acorn nutsll' and machine screws 18. A suitable top19 may be provided on top of the highest unit.

- While the invention has been described above in its preferred form, itwill be obvious that various changes and modifications maybe madetherein without departing from the spirit or scope thereof and it istherefore desired that only such limitations may be imposed thereon asare'ne'cessitated by the prior art or specificallyset forth in theappended claims. i

I claim as my invention and desire to secure by Letters Patent of theUnited States:

1. As a new and improved article of manu-. facture, a correspondenceunit comprising a single sheet bent up at three sides, forming a foursided bottom and three upstanding walls, said walls having their edgeparts bent inward with the corner portions of said edge parts lapped atthe two meeting corners of the sides.

2. As a new and improved article of manufacture, a correspondence unitcomprising a single sheet bent up at three sides, forming a four sidedbottom and upstanding walls at opposite'sides and the rear, said wallshaving their edge parts bent inward'to form flanges with end portions ofsaid flanges lapped at I the two meeting corners of the side and rearwalls and having openings, one through each two lapping end portions ofthe side and rear flanges, and one through the opposite end part of eachflange, said bottom having openings substantially vertically alignedwith the flange openings, spacing walls and having openings,- onethrough each two lapping end portions of the side and rear.

flanges, and one through the opposite end part of each side flange,-said bottom having. openingssubstantially vertically aligned with the,flange openings, foot members, one foot member secured in each bottomopening, spacing 7 members, and means whereby said spacing members mayflange and bottom openings of two like correbe secured in the respectivespondence units.

,4. As a new and improved article of manufacture, a correspondenceunit/comprising a single sheet bent up at three sides, forming a foursided bottom and upstanding walls at opposite sides and thereansaidwalls having their edge parts bent inward to form flanges to preventaccidental escape of papers from said unit, said Walls being of suchheight and their flanges thus being so spaced up from thebottom thatpapers placed on said flanges may fall by fiexure down past the flangesinto the unit, the fourth side of said bottom being devoidofobstr'uction'to such extent as to allow .the papers to be picked upandiremoved freely at said edge, and the walls and their flanges meetingat the rear to prevent wedg ing of the rear corners of the papersbetween them. a I
